This sounds like a wiring problem. This is a millivolt reading so it is very sensitive to any poor connection. Ideas: Check to make sure all crimps are clean and tight clean the connecti...
I am going to include Al fromWakespeed in this thread and see if he can provide any insight. @Al Thomason @Rick Admin
Guys, after talking with Al, he confirmed that the WS500 does not integrate with CVCC yet. From Al \"And at all times the WS500 directly takes its guidance from the BMS -- Victron has not extend...
I would think you only need 2.9-2 if you have an older system and do not have the Wifi module
No, its a setup screen in the \"Tasks\" tab of the WiFi module, with several parameters and alarms that can be configured
As per my other post you will likely find what you need using the Tasks feature in the WiFi module. I would use an opto output as your charger interlock and set it up in Tasks while the relay is u...
Yes, all parameters are programmable by either the PC software or the Wifi. The only difference is that with the new firmware there is a new feature called Tasks that also allows custom configurat...
Hey Nathaniel, I see you posted this to the Victron Venus github project as well. I also just reached out to Al at Wakespeed to see if he could offer any insight.
Missed that one. Getting the details and hope to have it posted in the next few days Thanks for the heads up
I had a quick look over your pics. Nice that you included them. I see that you have your low voltage hysteresis (deadband) set to what looks like 1 V. The is the RE1L parameter that Ben is refer...
Hey Johnny, this is one we will have to push back to Wakespeed for a reply. Copy to Al at Wakespeed @al-thomason
Thanks for your kind words. We have several more detailed videos in the works too. Think of port forwarding in old land line terms. It\'s the same as directing an outside line to ring at a cer...
Sure, the WiFi module can be configured as a AP (Access Point) or STA(Station) device on your home network. Then you just need to map it in your home router using port forwarding. Here is a tut...
Hi Matthew, As long as you have a 120 ohm terminator on each of the longest ends, with only short branch stubs you should be fine. Your best bet is to try and have one continuous cable so remov...
Hey Giorgio, this is pretty cool. I havent played with this feature in a couple of years and its great to see it now integrates well. Thanks for sharing! The engine speed is calculated based ...
Missed this one. The IOS app is for offline setup only. IOS does not allow the use of the port for 3rd party serial USB functions like Android does. The idea is that you configure it, send ...
This is good information Al, thanks for jumping in. And to confirm yes, REC BMS does support a 48V LFP Victron/WS500 integrated system in both a single SI-Q Series BMS or up to 15 strings of cells...
Ben has some good ideas and I think he is correct in suspecting your alternator is the problem. Second step after that would be to check the wires inside the AMP connector for chafing. If neithe...
The sensors are smart devices and the 3 wires in the sheath just get paralleled together to the second sensor to create a sensor network. We are working on a more elegant solution but all you need...
Your installation seems to be well designed based on your overview and having a separate 12/48V system is actually quite common so I am not sure why they would say something like this. Al is or wa...
and here is a 2P4S wiring diagram from the REC BMS North America site you can use as a starting point https://rec-bms-na.com/download/31/rec-active-bms-sketches/1290/rec-active-bms-wiring-diagra...
Sounds like a great config and yes, the Active BMS is good to about 1,000Ah of well behaved \"A\" grade cells like CALBs. FYI, for large scale 12V projects there is a Master/Slave solution but y...
Not sure exactly what you are looking for but Al put together a pretty detailed setup and communications manual that might help. Here is the link https://www.wakespeed.com/wp-content/uploads/...
We have posted some new Active and SI-Q series diagrams to the REC North America site which use the new PreCharge V3 module and show both a 2P4S and 2P8S configuration for those who were wondering ...
REC has just released a firmware update for the Active BMS that adds a new CAN message and addresses an RS485 bug. For details and downloads you can visit the REC North America site here: https...
I grabbed this page snip from page 13 of the Active BMS manual. Manuals are available here: https://rec-bms-na.com/downloads/
The Active BMS and Master both have a Real Time Clock(RTC) but the SI-Q series standalone does not. Time can be set in the Firmware tab of the WiFi module. From the manual Firmware tab is us...
yes, but REC was closed over the holidays for more than 2 weeks. It normally only takes a few days. I would expect to see it early next week
Both Trond and Ben make a very good point. To switch an alternator is usually as easy as finding the brush wire that goes to the diode bridge and moving it to ground instead. Your other brush the...
Yes it is possible but Wakespeed does not share this information freely as they say incorrect configuration can cause serious damage. If you contact them directly they may be able to help.
Hey Stefano, Not quite sure what is happening with the new company but we have been trying to give them some constructive feedback and fortunately we have a great bunch of people with WS500 expe...
The comma after the custom table 7 or 8 is not required. If you have a PC and our WS500 config tool you can upload your current parameters and verify they were correctly posted. Also, when you ar...
The first place to start is with your wiring. The current shunt sense wire measures a very low milli-volt signal and is susceptible to outside interference. Make sure the wires are not near or wo...
Ed, for some reason I thought your RV was 12v. Busy day🤪. For a Q Series you need to send us your serial number to tech@offgridsoftwaresolutions.com as each firmware build is keyed to your BMS. ...
The Cerbo will also recognize the REC BMS and a couple of Smart batteries, but I would expect your BMS to work. Have you enabled DVCC in your Cerbo? Here are the instructions for connecting you...
I havent yet configured an all Victron to WS500 solution with the updated firmware and new Cerbo rev, but here are a couple of things to consider Do you have the correct WS500 profile for Victro...
Good feedback, thanks, but most people wire the WiFi module to the battery side of the system and leave it powered up. The current draw in sleep mode is so tiny as to be not a factor. The benefit...
Hey Jeremy, Its a 50/50 chance and all depends on what cell sequence you connected them in. For instance, if you connect cell 1 -, then cell 4 +, you have put 13-14 volts on a 5V ADC module, or...
Tine has provided an updated 2.8.1 firmware bin file for the Active BMS. When asked how he implemented the low temp change, this was his reply. \"No buzzer on the BMS but sent to the inverter a...
